Libvit development team reports:

+
Various virStorageVol* API operate on user-supplied volume names by + concatenating the volume name to the pool location. Note that the + virStoragePoolListVolumes API, when used on a storage pool backed by + a directory in a file system, will only list volumes immediately in + that directory (there is no traversal into subdirectories). However, + other APIs such as virStorageVolCreateXML were not checking if a + potential volume name represented one of the volumes that could be + returned by virStoragePoolListVolumes; because they were not rejecting + the use of '/' in a volume name.
+
Because no checking was done on volume names, a user could supply + a potential volume name of something like '../../../etc/passwd' to + attempt to access a file not belonging to the storage pool. When + fine-grained Access Control Lists (ACL) are in effect, a user with + storage_vol:create ACL permission but lacking domain:write permssion + could thus abuse virStorageVolCreateXML and similar APIs to gain + access to files not normally permitted to that user. Fortunately, it + appears that the only APIs that could leak information or corrupt + files require read-write connection to libvirtd; and when ACLs are not + in use (the default without any further configuration), a user with + read-write access can already be considered to have full access to the + machine, and without an escalation of privilege there is no security + problem.
